The Lands of the Bohemian Crown were the states in Central Europe during the medieval and early modern periods with feudal obligations to the Bohemian kings. The crown lands primarily consisted of the Kingdom of Bohemia, an electorate of the Holy Roman Empire according to the Golden Bull of 1356, the Margraviate of Moravia, the duchies of Silesia, and the two Lusatias, known as the Margraviate of Upper Lusatia and the Margraviate of Lower Lusatia, as well as other territories throughout its history. This agglomeration of states nominally under the rule of the Bohemian kings was referred to simply as Bohemia.
The joint rule of Corona regni Bohemiae was legally established by decree of King Charles IV issued on 7 April 1348, on the foundation of the original Czech lands ruled by the Přemyslid dynasty until 1306. By linking the territories, the interconnection of crown lands thus no more belonged to a king or a dynasty but to the Bohemian monarchy itself, symbolized by the Crown of Saint Wenceslas. During the reign of King Ferdinand I from 1526, the lands of the Bohemian Crown became a constituent part of the Habsburg monarchy. A large part of Silesia was lost in the mid-18th century, but the rest of the Lands passed to the Austrian Empire and the Cisleithanian half of Austria-Hungary. By the Czechoslovak declaration of independence in 1918, the remaining Czech lands became part of the First Czechoslovak Republic.
